摘要： A system for converting operation of a valve between an unbalanced operation mode and a balanced operation mode includes a housing adapted to couple to a valve body. The system also includes a lower stem, including lugs, the lugs having a lug diameter that is larger than an adjacent lower stem diameter. The system further includes a valve member nut coupled to a valve member, the valve member nut having an opening to receive the lower stem, and pins extending into the opening, the pins forming a reduced diameter portion of the opening. In the system, the lower stem couples to the valve member, via the valve member nut, when the lugs are axially aligned with the reduced diameter portion and the lower stem decouples from the valve member when the lugs are axially misaligned with the reduced diameter portion.

摘要： The disclosure describes hydrocarbon flowline corrosion inhibitor overpressure protection. Such a protection system includes a fluid flow pathway fluidically coupled to a corrosion inhibitor injection pump that injections corrosion inhibitor into a hydrocarbon carrying flowline. When the injection pump pressure exceeds a threshold flow pressure, the corrosion inhibitor is flowed through a first branch of the fluid flow pathway to relieve the excess pressure. The first branch is fluidically isolated from a second branch. When a rupture disc in the first branch fails, then the corrosion inhibitor is diverted to flow through the second branch and the first branch is isolated from the corrosion inhibitor flow.

摘要： This disclosure presents an apparatus to improve the indication of an amount that a fluid valve is opened. The fluid control assembly includes an improved position sensor assembly (PSA), where the PSA uses rollers rather than sliding within the PSA housing. The rollers, which can be wheels, ball bearings, and other types of rolling devices, can reduce the friction experienced by the moving component within the PSA. Since the PSA mechanism can move with less friction, the coupled valve magnetic assembly (VMA) can also be enhanced. The VMA can utilize magnets in orientations that enhance the magnetic tensile and compressive forces. For example, some magnets in the VMA can be in a perpendicular orientation to improve directional control and some magnets can be in an angled orientation to reduce the spread of the magnetic field flux lines between the magnets of the VMA and the magnets of the PSA.
